ti5x is an emulator, running on Android, for the venerable TI-58/58C/59 family of programmable scientific calculators which were manufactured by Texas Instruments from the late 1970s.
ti5x does aim for 100% authenticity even if not possible in all cases. Yet, it supports many undocumented features from the original calculator like the HIR registers and the /DSZ nn 51/ (decrement no-jump) instructions.
With the current version it is possible to play the famous Treasure-Island and 3D-Tic-Tac-Toe games.
The saved programs where stored into the Programs directory at the root of the file system. Since Android-10 it is not possible anymore to access this location for security reasons.
The programs are now saved into
Android/Data/net.obry.ti5x/files/Programs
You need to manually move the programs from Programs/*.ti5p to Android/Data/net.obry.ti5x/files/Programs to get access to them with version 7.9.
